- modules/entrybleed_cve_2023_0458/ (promoted out of _stubs):
- iamroot_modules.{c,h}: full EntryBleed primitive (rdtsc_start/end
+ prefetchnta + KASLR-slot timing sweep) wired into the standard
iamroot_module interface. x86_64 only; ARM/other gracefully
return IAMROOT_PRECOND_FAIL.
- detect(): reads /sys/.../vulnerabilities/meltdown to decide
KPTI status. Mitigation: PTI → VULNERABLE. Not affected → OK.
- exploit(): sweeps the 16MiB KASLR range, prints leaked kbase
(and KASLR slide). JSON-mode emits {"kbase":"0x..."} to stdout.
- entrybleed_leak_kbase_lib(off) declared as a public library
helper so future LPE chains needing a stage-1 leak can just
#include the module's header and call it.
- entry_SYSCALL_64 slot offset overridable via
IAMROOT_ENTRYBLEED_OFFSET (default 0x5600000 for lts-6.12.x).
- __always_inline fallback added since glibc/Linux-kernel macro
isn't universal; module now builds clean under macOS clangd lint
and on musl.
- iamroot.c registers entrybleed alongside the other families;
Makefile gains it as a separate object set.
Verified end-to-end on kctf-mgr (Debian 6.12.86):
iamroot --exploit entrybleed --i-know
→ [+] entrybleed: leaked kbase = 0xffffffff8d800000
This is the FIRST WORKING-EXPLOIT module in IAMROOT (5
copy_fail_family modules wrap existing code from DIRTYFAIL;
dirty_pipe is detect-only). EntryBleed is x86_64 stage-1 brick
that future chains can compose.

# IAMROOT — top-level Makefile (Phase 1)

#
|
|
# Builds one binary `iamroot` linked from:
|
|
# - core/ module interface + registry
|
|
# - modules/<f>/ one family per subdir, contributes objects to the
|
|
# final binary
|
|
# - iamroot.c top-level dispatcher
|
|
#
|
|
# Each family is currently flat (Phase 1 keeps copy_fail_family's
|
|
# absorbed DIRTYFAIL source in modules/copy_fail_family/src/).
|
|
# Future families register the same way: add their register_* call to
|
|
# iamroot.c's main() and add their src dir to MODULE_DIRS below.
